One such transformational task is converting JSON (JavaScript Object Notation) into XML (eXtensible Markup Language). If you're using Dataweave — a powerful transformation language used in MuleSoft — you might encounter challenges when you need to exclude null or empty fields during the conversion process. This guide will guide you through the process step-by-step. Understanding the Input JSON Before diving into the transformation logic, let's take a look at our input JSON structure: [[See Video to Reveal this Text or Code Snippet]] In this example, our JSON consists of several fields. Note that some fields, like Inspected__C, Work Complete__C, and Billing Complete__C, are empty strings. Our goal is to convert this JSON into XML format without including these empty values in the output. Transformation Logic in Dataweave To convert our JSON to XML, we will use the following Dataweave script: [[See Video to Reveal this Text or Code Snippet]] Breaking Down the Logic Setup: This script starts by declaring the format to be XML and establishes the output structure with XACTDOC as the root element. Mapping Input: It then uses the map function on the payload, which iterates over the array of JSON objects. Conditionally Adding Attributes: For every field that we want to convert to an XML attribute: It checks if the respective JSON value is not empty using !isEmpty(). If the condition is satisfied, it adds that field to the CONTROL_POINT node as an attribute with the @ symbol denoting attributes in XML. Result: This ensures that only fields with values are included as attributes in the final XML output. Example Output When we run the transformation on the example JSON provided, the output will resemble the following XML structure: [[See Video to Reveal this Text or Code Snippet]] Notice that the empty fields do not appear in the XML, fulfilling the requirement to clean up the output. Conclusion Converting JSON to XML in Dataweave can be straightforward with the right approach. By leveraging conditional checks to include only populated fields, you can ensure your transformation outputs clean and relevant data. Whether you are working with complex datasets or simple ones, understanding how to manipulate the structure effectively is key to successful data integration with MuleSoft. In summary: Start with clear JSON structure. Employ Dataweave's transformation capabilities to map values conditionally. Ensure clean, relevant XML output by excluding empty values.
